Plant project excels
AN AWARD winning project at the Biggenden Sewerage Treatment Plant has drawn interest from an Indonesian Local Government.
They are looking at a similar project that would cover 85ha and service one million people.
At the recent Institute of Public Works Engineers Australia (IPWEA) State Conference the North Burnett Regional Council was awarded the 2014 Engineering Excellence Award for projects under $1 million.
NBRC technical services manager Trevor Harvey displayed the awards at Tuesday’s general meeting at Biggenden.
Accepting the award, acting mayor Cr Faye Whelan said the team needed to be congratulated.
“You should be very proud of your efforts with this innovative idea,” Cr Whelan said.
Mr Harvey said the upgrade involved the renewal of various sections of the 40-year-old plant, along with the conversion of the third lagoon to a subsurface rock filter.
“The project was completed on time and under budget with about 70% local and regional labour content,” he said.
“The original project scope encompassed an upgrade of all elements of the treatment plant to defer the requirement of constructing a new plant in four years’ time.
“The results since bringing the plant online have shown excellent water quality, no increase in power consumption and a reduction in chemical addition.”
The project is expected to eliminate the need for a new plant at a possible saving of up to $4 million to council.
The results of the subsurface rock filtration have led to other local governments both in Queensland and overseas planning to use the filters.
Mr Harvey has also presented four papers on the rockfill filtration.
